OP always do your research since KYC Free is not always there, expect that it can still be asked especially if you are going to deposit huge money for your gambling activities.
That's why we have this thread because OP wants to get some information based on our experience and our opinion. We have a lot of gambling sites here, some maybe have scam accusations but it's up to OP to weigh things out, whether he will take the risk or go for a reputable site based on the feedback here, in the end, what matters is the personal experience.
I don't want to endorse a site about their reputation whatsoever, but at least OP would know the reputation based on certain factors.
In this forum, you can check the account's profile and you'll see the explanation of feedback.
As for me, it would be better to register on a casino site that asks for KYC than to risk my funds on a casino site that doesn't ask for KYC but has a bad reputation. Reputable sites that ask for KYC will surely protect your identity so submitting a KYC as long as you have the requirements I think will never be a problem.
